Hung ceilings, because of the nature of their construction,
tend to act as sounding boards and amplify the noises and vibrations
that are transmitted down from the building structure through
the suspension wires. Just the opposite is the situation with
air ducts and piping in that vibration from air handling units
and pumps is transmitted to the building structure. In order
to reduce these effects, a completely resiliant material must
be interposed in the system. The 'ARH-1' Hanger is designed
to server just this purpose.

Specifications

Isolation
hangers shall be incorporated, in series, into the suspension
system at all points of support. The isolation medium shall
be high tensile gum rubber, to assure resilience, with an anti-ozonant
added, to assure long life. The metal structural portion of
the hanger shall be 11 gauge zinc coated steel wire forms interlocked
through holes in zinc coated steel pressure plates and swaged
in place to provide failsafe construction. Rubber collars shall
be provided at the points where the wire forms pass through
the pressure plates to prevent metal-to-metal contact.
